Application filed August 30, 1913.

To' a'ZZ'wFwm' it may concern Be-it known that we, HERBERT F. ProvvAlanna and itmvm H. VVHITNEY, citizens of the United States, residing at Melrose and Rehohoth, respectively, in the counties of Middlesea: Bristol and State of Massachusetts, have invented an Improvement in Machines for Cutting Bottom {P eces for Paper Cups, of which the following' is a specification.

This invention relates to a machine for hottompieces for paper cups and other receptacles.

-The machine embod'ing this invention involves taking a strip of paper from a roll and passing it between a pair ofprintingrolls by which it is printed on one or-both sides, at regular intervals, and then passing it to a pair of feed-rolls which act to feed forward the strip, and in case it is required that the hottom-piecesshall have deposited upon them a small quantity of parafin-Wax the lower feed-roll is arranged in a reservoir containing? liquid paraffinwax, and upon rotation -of said roll a thin layer. is deposited on the under side of the strip. The strip then passes to another pair of feed-rolls, and between the two feed-rolls the strip may be reversed, if depunch and die through which the bottom-pieces are forced sired, to bring the paraiiin-coated'side uppermost, and, in such case, reversing-means is arranged between said two pairs or" feed rolls. The strip then passes to a punch and die by which the bottom-pieces are cut from the strip and are forced down into and through the die; and associated with said is a flange-forming means by a suitable plunger formed on them. The strip from which the sen out passes between a-pair of feed-rolls and by said rolls is fed forward in a direction away from the machine.

Figure 1 is a front elevation of the machine for cutting and hanging bottom-pieces embodying this invention. F ig. 2 is an enlarged plan view of the left-hand end-portion of. the machine shown in Fig. 1. Fig. 3 is an enlarged plan View of the right-hand end-portion of the machine shown in Fig. 1, the punch and operating-means therefor being removed.

Fig. 7 is a detail of the clutch of the intermittent actuating-means. Fig. 8 is a detail of one pair of feed-rol1s for the strip having means for effecting a quick ad ustment'of one of the rolls to move it into and out of engagement with the strip. Fig. 9 is a transverse vertical section of one pair of food-rolls and reservoir adapted to ucontain liquid paladin-wax in which the lower feed-roll of the pair rotates. Fig. 10 is a view of one of the bottom-pieces which is cut from the strip and has a marginal flange formed on it.

represents a strip of paper in the form of a roll which is of any suitable kind, quality and thiclniess, such for instance. as cardboard. Such a 011 may be composed of numerous short pieces pasted or otherwise secured together. The strip 1Q passes over suitable guides, as 12 and 13, to a rotary pi'intingdevice, here shown as a pair of printingrolls 15, arranged horizontally one above the other and adapted to receive the strip between them, and to print upon one or both sides of the strip, as occasion may require. These printing-rolls are of any suitable construction. so far as this invention is concerned. The strip 10 then passes to a pair of feed-rolls 18, l9,-arranged horizontally one above the other and geared together, and adapted to receive the strip between them and to feed it'forward and also, as here shown, said feeding-rolls are employed to deposit on one side of the strip a thin layer of liquid paraifin-wax which subsequently solidifies thereon, and, for the ac: complishment of this result. the lower feedroll is employed as the roll to deposit the liquid. paraflinwvax upon the strip. ,Said roll, therefore, is arranged to rotate in a reservoir 20 of any suitable shape and size, adapted to contain liquid paladin-wax, there being a'suitahle heating-device arranged in sai reservoir for maintaining the wax in supported {at one side of the reservoir, Which is'heldin yielding engagement with the roll 19, by means of a spring, 23, thereby to regulate the quantity of li. ,uid paraiiin- Wax which said roll shall deposit upon the strip The strip then continues forward standard the strip is deflected from the horizontal position to the vertical position and by means of the edge-guides is subsequently deflected from asvertica'l position to a horizontal osition, so that while passing from the fee -rolls 1B, 19, to the. feed-rolls- ?0, 31, its position is reversed. In case it is not necessaryto reverse the strip said rereaming-means will be omitted Referring to Fig. 8 showing the second pairof feed-rolls 30, 31, it will he observed that a quick adiusting-means is provided for the upper roll SO consisting-of a handlever 32 connected to a'coarse pitch adjusting-screw 33. Such adjustment is desirable in loca izing the printing-strip with respect to the punch and die, to be hereafter de-' scribed.

The strip 10 is fed forward by the feedrolls 30, 31, to a punch andldie by which bottom-pieces of any suitable size and shape,

are cut therefrom, and-said punch and die are or, may be of any suitable construction, so far as this invention is concerned, and,

- as here shown, 35 represents the punch and 36 a stripper-plate and 37 a die-plate which latter is located beneath the stripp'er platc.

' Said punch is secured to the lower end of a vertically reciprocating slidingEoTm/AO,

which is operated by an eccentric 41 secured positively to a shaft 42. v

Arranged beneath the punch and die is a fianging-device by which a marginal flange is formed-on the bottom-piece, and, as here shown, said flangingdevice consists of a hanging-ring 45, arranged beneath and cone centric to the die, andaplurality of radially disposed fingers 46, are arranged beneath the flangiug-ring which are yieldingly supported against outward radial movement by :1;

a spring-57, and a longer 48 is a'f-ranged withinaha} concentrically to the punch and of suitable shape and size to pass through the llangmgring and yieldingly supported fingers and acts in coii'peration therewith to' turn up a flange on the edge of the hottompieces. The fianging-ring acts to form the flange, and the fingers respectively engage the numerous projections at the edge of the flange, and act to bend said projections in- Word, so that, the, flange will be formed at a pronounced right angle, instead of being bevel-gear 70,

allowed "tci'bend'bachward owingto'the resiliencj v of the paper. 'As the punch is rc-' ciprocatecl its operation is intermittent, and hence the strip 10 is fed forward intermittingly, and, fertile accom lishment of this result a cam 50is secure to the shaft 42, which engages a ivoted lever 51, havin connected therewit the upper. end of a rod 52, having at its lower end a rack-bar 53, which engages a gear-wheel 54, loosely mounted to oscillate on ahhaft 55, and said oscillating gear-wheel supports one or more pawls 56, which engages aratchet toothed wheel 57, securedi'to saidflshait 55.- The shaft has a geanwheel 60 secured to it which engages a pinion 61, which in turn' engages a gear-wheel 62 on the lower feed roll 31, thereby to intermittingly drive said feed-roll. The shaft of the lowenfeed-roll 31- is extended forward and has securedto it a bevel-gear 65, which engages 11 based gear 66, securedto a shaft 67, extended hcri z'ontally, lengthwise the machine-frame, and said bevel-gear shaft has secured to it a. which engages a bevelcar 71, on the shaft of the upper feed-r01 18,

thereby ,to intermittingly rotate said feedroll, and said forward gear-shaft also has engages a bevel-gear 76, secured to the shaft of the upper printing-roll is, thereby to ineermittingly rotate said printing-roll. in here shown for interm1t-.

tingly rotating the several". rolls anyother secured to it another bevel-gear 75, which means maybe employed. 1 v

For the purpose of reipcvin thewaste portion of the strip 10 from t emachme after the bottom-pieces have been out there from a pair of horizontally rolls 80, 81, are located l'begond thev punch arranged-icedand die, which are geared together andlona'i of which is adapted to cnchas here shown, the upper feed-roll untothe aforesaid feed-rolls, and said upper feed-roll" shaft has secured cont a which is engaged by a gear wheel 83, secured to a shaft 84, hearings; I sprocket-wheel gear-wheel 82,
